Re: [AFMUG] BNG dynamic provisioning Re: strange outage

Sat, 19 Jun 2021 05:25:16 -0700

We have in each tower a ubiquiti switch and one or two APs plus an uplink(to next tower towards the gateway) and a downlink(away from the gateway).  We don't have that many customers to support a huge investment.
Ok, looks like the advice is to replace the ubiquiti switches with ubiquiti routers?  I haven't seen in router setup any provision for BNG, maybe I'm missing something.  I'd never get management willing to replace a $100 switch with a $3,000 Cisco router, especially on a network where we wouldn't make that much ROI in several years (we have a board of directors who keep threatening to shut us down, they're mostly from last century and barely know how to use a cell-phone). 


Am I wrong in thinking we can configure an Edgerouter X to prevent these 
multicast storms we're having in our networks?  I'm loathe to use any 
natting, can I leave these in bridge-mode and get a solution to the problem?

I get really tired of the ‘experts’ telling everyone there is only one 
‘right’ way to build a network, yet have never heard of this.

We use the same BNG for all our residential subs in a market.  GPON, 
Active Ethernet, and Fixed Wireless.  Some of the fixed wireless 
stuff requires a hack to run the CVLANS through another box to add 
the second tag but that's cheap and easy enough. A Netonix 6 mini 
hanging off a switch can do it with either 0x88a8 or a second 0x8100 
tag.  Cambium supports QinQ natively.

    Thanks.  This seems fairly common on GPON
    networks as well so you could use this feature
    for both GPON and Fixed Wireless on the same BGN.
